Fake Glowing Plutonium

I made this to creep out my house mates. It is a glowing  pot of "polonium" with a radiation sign on it.  As a joke I left it in my cuboard to confuse and stop the phantom cookie thief of our diggs.

What you need:

• Glass spice pot
• Printer
• Coloure changing foam light stick (for raves)
• UV reactive powder (I got mine from here)
• UV LED
• Spray mount glue (aerosol type)
• A scaple or sharp knife

Simple Version: Will glow at a reduced brightness over a long period of time

1. Spray the inside of the glass jar with the spray-mount glue
2. Coat the inside of the jar with a mix of aqua blue and spooky green UV gowing powder..
3. Allow the glue to dry.
4. Print out the small radiation sign.
5. Stick the sign on the jar with some more, spray mount glue
6. Finally place on your windowseal or under a desk lamp to charge up the powder.
7. You have now finished, just switch off the lights and watch it glow for hours upon hours.

More Complex: Gives a cool pulsing & throbing effect due to a UV led (Much Brighter)

1. Spray the inside of the glass jar with glue
2. Coat the inside of the jar with a mix of aqua blue and spooky green UV gowing powder and allow to dry.
3. Print out the small radiation sign
4. Stick the sign on the jar with some more, spray mount glue
5. Remove the light module from the foam by cutting it out.
6. Desolder the 3 LEDs.
7. Replace the blue led with a UV LED, this is because the blue and UV LEDs have similar operating voltages.
8. Place the newly made UV LED module in the top of the jar and screw the origanal jar lid on top of that.
9. Finally turn the light module on You are done !!
